i IMPROVED APPARATUS FOR `COATING AND FLOCKING CLOTH.

Specification forming' part of Letters Patent No. 44,281, dated September 2U, 186i.

To all whom zt may concern Be it known that I', EDWIN M. CHAFFEE, of the city land county-1 of Providence, State ot' Rhode Island, have invented a new and Improved Machine for Goatingv and' Flocking Cloth, 83e.; and I do hereby declare that` the following is a full, clear, and exact description thereof, which will enable those skilledl in the art to make and use the same, reference bein g had to the accompan'ing drawings, forni ing part this specification, .in which- Figure l represents a longitudinal vertical section of this invention. Fig. 2 is a side eleration of the same. Fig 3 is an end view of the same. y

Similardctters of reference indicate correspending parts.

The object of this invention is to coat cloth 'or textile fabrics in'pieccs one thousand (more or less) yards long by machinery which applies the requisite coat of water-proof or other composition or varnish and thevoeks, it desired, and at the same time conveys the cloth to a drying-room, and hangs it' in folds upon sticks or slats automatically. The long pieces ot' cloth are made up of shorter ones, cemented er sewedtogether as for calendering.

The process of coating is effected while the (l th is being conveyed tothe drying-room,

and the machine at the same time delivers a series of newly-arranged lattice-frames, which are supplied to it at suitable intervals, and upon the slats or rounds of these frames the cloth is deposited in folds, four or more yards npon each Slat, according to the height of the room;

The cloth to be coated, varnished, or docked is unwonnd from a roller, A, which has its the scroll, which is occupied by a bar,D, instead of a roller, andthe friction on this bar still further increases the tension ofthe cloth. From 'the bar D the cloth passes nndera knife,

doctor', or scraper, Eband before this doctor the water-proof' or other composition is placed, and as thecloth moves along-'under the doctor enough of the composition is left upon it to form one-,'coating. Behind this knife and within a few inches ot' it is a supporting-roll, l

c over thel pulley don the endof the shaft of said roller. Above and resting upon this roller is a. pressure-roller, H,`bctwcen ,which both cloth and ock pass, when oclrcloth is to beniamifactured,and it must be remarked that this roller is only used for flocking. The cloth then passes downward, and under the carrying-roller, I, the axle-of which has its bearings in the iower part of the iframe B, and which receives its motion byabel't, e, passing over pnlleyfj'g, as clearly shown in Fig. 2 of the'drawings.l From the roller I the cloth `passes in a hori-` zontal direction, or 'nearly so, to the carryingroller J, the axle of which forms the drivingshaft, by which motion is imparted to the 'various rollers. After passing through under roller J the cloth passes upward, and over -the roller K, thence in a horizontal direction to the delivery-roller L, over which 'it passes and descends to and between the slats of the lattice-frame M.

By referring to Fig. 1 of the drawings it will .be noticed that the cloth, which is repre-v sented'in red outlines, passes over the sev-y eral rollers without having' its coated surface come ineontact with either of them, and by the action of the irst roller C and 'bar D the requisite tensionisimparted to the cloth for the operation. The lattice-frame M rolls on castors upon a track, M', supported a short distance below the upper door of the dryingroom, and in the working-machine one of 'these frames after the other is removed out of it and into the drying-room through a narrow '-opening, whichdivides the machine from said drying-room'. i 0

An 'automatic intermittent motion 1s nneach frame by two long pins, It, projecting from the revolving shaft i. These pins catchsuccessively behind the several slats commencing with the first an'd mow the frame gradually to .let ,fall two toothed or rough surface-Wheels; j, which catch o ver the edges of the cloth and cause the saine to descend between the next succeeding slats or rounds. These two toothed wheelsj are supv ported upon arms'jcpyhieh are connected to short arms l by a limited flexible joint, or in passes the slat, both wheels drop with it, and

by means of the jointed arms k l they (the wheels) adjust themselves to crooked or oblique slats, and thereby/.they are enabled yto act upon the cloth with the desired ei'ect under all circumstances. The tension and all the carrying rollers are covered with emlery, or their surface is otherwise made rough.

The surface of the last or delivery roller ought to be made more rough or adhesive than the others, covering it with card-clothing, and the axle of said roller has its bearings on an extension of the frame B ldirectly over the rock-shaft lm, said extension being made to pass through the opening in the partition which separates the machine from the 'drying-room in such a manner as to allow the clothbto drop beyond the partition into the drying-room.

In order to permit the cloth to fall l several feet before it reaches the slats, the deliveryroller ought to be situated somewhat higherthan the top of the drying-room, er, if possible,

the machine ought to be made of such a height that the cloth will drop through one floor to the lattice-frames below, while the said frames may be, moved by machinery iu the same story with them.

The frames may be fed to the machine in any suitable manner, either one at a time by the tender,"or`by supplying a large number at a time, piled'fupone above thefother, and so situated that thel bottom frame is gradually moved from heneath the pile. v

In practice the frame A is placed ou a truck, so that it can be rcadilymoved from one place to another. This truck is not represented in the drawings.

I claim as new and ters Patent-' 1. The rollers A, C, F, Gr, l, J, K, L, and

doctor 1j), or their equivalents, arranged in re lation to each other and to the cloth substan.

tially in the manner herein described, so that long pieces ot` cloth can be coated and conveyed to the drying-room without bringing the face or varnished side of the cloth in contact with the rollers orv anything else except the ed ge of the doctor.

2. The employment or use of two toothed wheels, j, arranged substantially as herein specified to check the fall of the cloth at the desired interv-als. l'

3. The `jointed arms 7c l, in combination with the toothed wheels j, to act substantially as and for the purpose' set forth.

4. The combination of the rock-shaft Im, adjustable arms 7a l, and wheelsj, substantially as herein specified, to insure the simultaneous catching ot' both edges ofthe cloth.

,5. The employment ofthe lattce-fraxiies M substantially in the manner set forth for the purpose of supporting the cloth while in the drying-room. v
